Gas City High School, also known as the East Ward School, is a historic school building located at Gas City, Grant County, Indiana, United States. It was built in 1894, and is a two-story, square, Romanesque Revival style brick and stone building. A two-story Prairie School inspired addition was completed in 1923. The two buildings are connected by a two-story "bridge".
It is no longer used as a high school and is instead now used as the current administration building for Mississinewa Community School Corporation (MCSC).
It was listed on the National Register of Historic Places in 2004.
